Many people in Port Jefferson who end up in drug rehab are dual diagnosis clients with co-occurring mental and substance abuse problems. Actually, as many as 1/3 of those who struggle with mental health issues in Port Jefferson also become involved in substance abuse at some point in their lives. These dual diagnosis clients often turn to drugs or alcohol to self medicate as a way to alleviate the symptoms of an underlying psychological issue. Some addicts aren't even diagnosed with a psychological condition, and only when they begin to receive treatment at a drug treatment program is this sort of issue discovered. This alone can sometimes help resolve addiction issues and put the person in a position to receive treatment for both disorders so that they have a good chance of remaining clean and sober and psychologically stable in the future.
